The Skarven EVO GTX is Crispi's highest insulated boot available for women, designed for late season hunts or women whose feet run colder. A full grain Nubuck leather construction with a water repellent finish and a Gore-Tex lining keeps the moisture out and 800 grams of Gore's Duratherm XL Kelvin insulation keeps the warmth in. They come equipped with Dual Tech Lining (D. T.L.) – an inner lining that delivers high thermic insulation, extreme abrasion resistance, and naturally comfortable leather for 100% waterproofing and a long service life. To provide excellent stability on steep terrain, the Skarven EVO GTX feature Crispi's own A. B.S. S. (Ankle Bone Support System). Designed over the course of several years, the A. B.S. S. provides comfort and protection to the entire ankle area thanks to a combination of innovative materials to allow the footwear to contour gently your ankle. The Board Lasting Mechanical Construction achieves the perfect connection between torsion rigidity and flexibility thanks to a mechanical process that wraps the comfortable and soft part of the upper to the insole frame. Additionally, the Skarven EVO GTX are outfitted with Vibram soles for maximum traction in adverse terrain. Features of the Skarven EVO GTX: Dual Tech Lining (D. T.L.)A. B.S. S.
